Abstract : Alphonso mangoes are subject to internal breakdown, known as 'soft centre' or 'spongy tissue', during ripening and storage. This physiological disorder produces no external symptoms and a non-destructive means of predicting its incidence was sought. About 2500 mature but unripe fruit were graded according to specific gravity and ripened at 28 plus or minus 2 deg C. Fruits of sp. gr. 1.00 showed no internal breakdown but their quality was poor. Fruits of sp. gr. 1.00-1.02 showed 22% internal breakdown and those of sp. gr. > 1.02 showed 46% breakdown.
